2 1 ppendix : uxiliary Functions Introduction What are uxiliary Functions? Many PU set-up tasks involve the use of uxiliary (UX) Functions. The UX Functions perform many different operations, ranging from clearing ladder memory, displaying the scan time, copying programs to EEPROM in the Handheld Programmer, etc. They are divided into categories that affect different system parameters. You can access the UX Functions from irectsoft or from the L0 Handheld Programmer. The manuals for those products provide step-by-step procedures for accessing the UX Functions. Some of these UX Functions are designed specifically for the Handheld Programmer setup, so they will not be needed (or available) with the irectsoft package. Even though this ppendix provides many examples of how the UX functions operate, you should supplement this information with the documentation for your choice of programming device. Note, the Handheld Programmer may have additional UX functions that are not supported with the L0 PUs.

3 ppendix : uxiliary Functions ccessing UX Functions via irectsoft irectsoft provides various menu options during both online and offline programming. Some of the UX functions are only available during online programming, some only during offline programming, and some during both online and offline programming. The following diagram shows an example of the PL operations menu available within irectsoft. Menu Options ccessing UX Functions via the Handheld Programmer You can also access the UX functions by using a Handheld Programmer. Plus, remember some of the UX functions are only available from the Handheld Programmer. Sometimes the UX name or description cannot fit on one display. If you want to see the complete description, press the arrow keys to scroll left and right. lso, depending on the current display, you may have to press LR more than once.

4 ppendix : uxiliary Functions 1 UX * RLL Operations UX 1- Four UX functions are available to perform various operations on the control program. UX 1 - heck Program UX - hange Reference UX - lear Ladder Range UX - lear Ladders UX 1 heck Program oth the Handheld Programmer and irectsoft automatically check for errors during program entry. However, there may be occasions when you want to check a program that has already been in the PU. Two types of checks are available: Syntax uplicate References The Syntax check will find a wide variety of programming errors, such as missing EN statements, incomplete FOR/NEXT loops, etc. If you perform this check and get an error, see ppendix for a complete listing of programming error codes. orrect the problem and then continue running the Syntax check until the message NO SYNTX ERROR appears. Use the uplicate Reference check to verify you have not used the same output coil reference more than once. Note, this UX function will also find the same outputs even if they have been used with the OROUT instruction, which is perfectly acceptable. This UX function is available on the PL iagnostics sub-menu from within irectsoft. UX hange Reference There will be times when you need to change an I/O address reference or control relay reference. UX allows you to quickly and easily change all occurrences, (within an address range), of a specific instruction. For example, you can replace every instance of X with X. UX lear Ladder Range There have been many times when you take existing programs and add or remove certain portions to solve new application problems. y using UX you can select and delete a portion of the program. irectsoft does not have a menu option for this UX function, but you can select the appropriate portion of the program and cut it with the editing tools. UX lear Ladders UX clears the entire program from PU memory. efore you enter a new program, you should always clear ladder memory. This UX function is available on the PL/lear PL sub-menu within irectsoft. - L0 User Manual, th Edition, Rev.

5 UX * V-memory Operations UX 1 UX 1 - lear V-memory ppendix : uxiliary Functions UX 1 lear V-Memory UX 1 clears all the information from the V-memory locations available for general use. This UX function is available on the PL/lear PL sub-menu within irectsoft. UX * I/O onfiguration UX 1- Several UX functions are available to set up, view, or change the I/O configuration. UX 1 Show I/O onfiguration UX I/O iagnostics UX Power-up onfiguration heck UX Select onfiguration UX onfigure I/O UX 1 Show I/O onfiguration This UX function allows you to display the current I/O configuration. With the Handheld Programmer, you can scroll through each base and I/O slot to view the complete configuration. The configuration shows the type of module installed in each slot. irectsoft provides the same information, but it is much easier to view because you can view a complete base on one screen. UX I/O iagnostics This is one of the most useful UX functions available in the L0 system. This UX function will show you the exact base and slot location of any I/O module error that has occurred. This feature is also available within irectsoft under the PL/iagnostics submenu. UX Power-up onfiguration heck Select this feature to quickly detect any changes that may have occurred while the power was disconnected. For example, if someone placed an output module in a slot that previously held an input module, the configuration check would detect the change. If the system detects a change in the I/O configuration at power-up, an error code E NEW I/O ONFIGURTION will be generated. You can use UX to determine the exact base and slot location where the change occurred. WRNING: You should always correct any I/O configuration errors before you place the PU into RUN mode. Uncorrected errors can cause unpredictable machine operation that can result in a risk of personal injury or damage to equipment. This feature is also available within irectsoft under the PL/Setup sub-menu. 1 L0 User Manual, th Edition, Rev. -

6 ppendix : uxiliary Functions 1 UX Select onfiguration Even though the PU can automatically detect configuration changes, you may actually want the new I/O configuration to be used. For example, you may have intentionally changed a module to use with a new program. You can use UX to select the new configuration, or, keep the existing configuration that is stored in memory. This feature is also available within irectsoft from the PL/Setup sub-menu. WRNING: Make sure the I/O configuration being selected will work properly with the PU program. You should always correct any I/O configuration errors before you place the PU into RUN mode. Uncorrected errors can cause unpredictable machine operation that can result in a risk of personal injury or damage to equipment. UX onfigure I/O The L0 1 and L0 PU allows you to use UX to manually assign I/O addresses for any or all I/O slots on the local or expansion bases. It is generally much easier to do the I/O configuration operations from within irectsoft. The software package provides a really nice screen that is available from the PL/onfigure I/O sub-menu. This feature is useful if you have a standard configuration you must sometimes change slightly to accommodate special requests. For example, you may require two adjacent input modules to have addresses starting at X and X00 respectively. In automatic configuration, the addresses were assigned on -point boundaries. Manual configuration assumes that all modules are at least 1 points, so you can only assign addresses that are a multiple of 0 (octal). For example, X0 and Y0 would not be valid starting addresses for a module. X0 and Y0 are valid examples of starting addresses in a manual configuration. This does not mean you can only use 1- or -point modules with manual configuration. You can use -point modules, but 1 addresses will be assigned and of them are unused. WRNING: If you manually configure an I/O slot, the I/O addressing for the other modules will change. This is because the L0 products do not allow you to assign duplicate I/O addresses. You should always correct any I/O configuration errors before you place the PU into RUN mode. Uncorrected errors can cause unpredictable machine operation that can result in a risk of personal injury or damage to equipment. Once you have manually configured the addresses for an I/O slot, the system will automatically retain these values even after a power cycle. You can remove any manual configuration changes by simply performing an automatic configuration. - L0 User Manual, th Edition, Rev.

7 ppendix : uxiliary Functions UX * PU onfiguration UX 1- Several UX functions are available to set up, view, or change the PU configuration. UX 1 Modify Program Name UX isplay / hange alendar UX isplay Scan Time UX Initialize Scratchpad UX Set Watchdog Timer UX PU Network ddress UX Set Retentive Ranges UX Test Operations UX it Override UX ounter Interface onfiguration UX isplay Error / Message History UX 1 Modify Program Name The L0 products can use a program name for the PU program or a program stored on EEPROM in the Handheld Programmer. Note, you cannot have multiple programs stored on the EEPROM. The program name can be up to characters in length and can use any of the available characters ( Z, 0 ). UX 1 allows you to enter a program name. You can also perform this operation from within irectsoft by using the PL/Setup sub-menu. Once you ve entered a program name, you can only clear the name by using UX to reset the system memory. Make sure you understand the possible ramifications of UX before you use it! UX isplay/hange alendar The L0, L0 1, and the L0 PUs have a clock and calendar feature. If you are using this, you can use the Handheld Programmer and UX to set the time and date. The following format is used. ate Year, Month, ate, ay of week (0, Sunday through Saturday) Time -hour format, Hours, Minutes, Seconds You can use the UX function to change any component of the date or time. However, the PU will not automatically correct any discrepancy between the date and the day of the week. For example, if you change the date to the 1th of the month and the 1th is on a Thursday, you will also have to change the day of the week (unless the PU already shows the date as Thursday). You can also perform this operation from within irectsoft by using the PL/Setup submenu. 1 L0 User Manual, th Edition, Rev. -

8 ppendix : uxiliary Functions 1 UX isplay Scan Time UX displays the current, minimum, and maximum scan times. The minimum and maximum times are the ones that have occurred since the last Program Mode to Run Mode transition. You can also perform this operation from within irectsoft by using the PL/ iagnostics sub-menu. UX Initialize Scratchpad The L0 PUs maintain system parameters in a memory area often referred to as the scratchpad. In some cases, you may make changes to the system setup that will be stored in system memory. For example, if you specify a range of ontrol Relays (Rs) as retentive, these changes are stored. NOTE: You may never have to use this feature unless you have made changes that affect system memory. Usually, you ll only need to initialize the system memory if you are changing programs and the old program required a special system setup. You can usually change from program to program without ever initializing system memory. UX resets the system memory to the values. You can also perform this operation from within irectsoft by using the PL/Setup sub-menu. UX Set Watchdog Timer The L0 PUs have a watchdog timer that is used to monitor the scan time. The value set from the factory is 00ms. If the scan time exceeds the watchdog time limit, the PU automatically leaves RUN mode and enters PGM mode. When the scan overrun occurs, the Handheld Programmer displays the following message: E00 S/W TIMEOUT. Use UX to increase or decrease the watchdog timer value. You can also perform this operation from within irectsoft by using the PL/Setup sub-menu. UX PU Network ddress Since the L0, L0 1 and L0 PUs have an additional communication port, you can use the Handheld Programmer to set the network address for the port and the port communication parameters. The settings are: Station address 1 HEX mode Odd parity You can use this port with either the Handheld Programmer, irectsoft, or, as a irectnet communication port. The irectnet Manual provides additional information about communication settings required for network operation. NOTE: You will only need to use this procedure if you have the bottom port connected to a network. Otherwise, the settings will work fine. Use UX to set the network address and communication parameters. You can also perform this operation from within irectsoft by using the PL/Setup sub-menu. - L0 User Manual, th Edition, Rev.

9 ppendix : uxiliary Functions UX Set Retentive Ranges The L0 PUs provide certain ranges of retentive memory by. The ranges are suitable for many applications, but you can change them if your application requires additional retentive ranges or no retentive ranges at all. The settings are: Memory rea efault Range L0 L0 L0-1 L0 vailable efault vailable efault vailable efault Range Range Range Range Range Range vailable Range ontrol Relays V-Memory V000-V V0-V V000-V V0-V V00-V V0-V1 V00-V V0-V Timers T0-T T0-T1 T0-T T0-T ounters T0-T T0-T T0-T1 T0-T1 T0-T1 T0-T1 T0-T1 T0-T Stages S0-S S0-S S0-S1 S0-S1 Use UX to change the retentive ranges. You can also perform this operation from within irectsoft by using the PL/Setup sub-menu. WRNING: The L0 PUs do not come with a battery. The super capacitor will retain the values in the event of a power loss, but only up to 1 week. The retention time may be less in some conditions. If the retentive ranges are important for your application, make sure you obtain the optional battery. UX Test Operations In normal Run Mode, the outputs are turned off when you return to Program Mode. In TEST-RUN mode you can set each individual output to either turn off, or, hold its last output state on the transition to TEST-PGM mode. The ability to hold the output states is especially useful, since it allows you to maintain key system I/O points for examination. See hapter for a description of the Test Modes. You can use UX to configure each individual output. You can also perform this operation from within irectsoft by using the PL/Setup sub-menu. 1 L0 User Manual, th Edition, Rev. -

10 ppendix : uxiliary Functions 1 UX it Override it override can be enabled on a point-by-point basis by using UX from the Handheld Programmer or, by a menu option from within irectsoft. it override basically disables any changes to the discrete point by the PU. For example, if you enable bit override for X1, and X1 is off at the time, then the PU will not change the state of X1. This means that even if X1 comes on, the PU will not acknowledge the change. So, if you used X1 in the program, it would always be evaluated as off in this case. Of course, if X1 was on when the bit override was enabled, then X1 would always be evaluated as on. NOTE: irectnet protocol does not support single-bit write operations. There is an advantage available when you use the bit override feature. The regular forcing is not disabled because the bit override is enabled. For example, if you enabled the it Override for Y0 and it was off at the time, then the PU would not change the state of Y0. However, you can still use a programming device to change the status. Now, if you use the programming device to force Y0 on, it will remain on and the PU will not change the state of Y0. If you then force Y0 off, the PU will maintain Y0 as off. The PU will never update the point with the results from the application program or from the I/O update until the bit override is removed from the point. The following diagram shows a brief overview of the bit override feature. Notice the PU does not update the Image Register when bit override is enabled. it Override OFF Input Update Force from Programmer Result of Program Solution X OFF Y OFF OFF Image Register (example) UX ounter Interface onfiguration UX is used with the L0 ounter Interface module -TRINT to select the module configuration. You can choose the type of counter, set the counter parameters, etc. See the L0 ounter Interface Module manual for a complete description of how to select the various counter features. X ON Y ON ON X1 ON Y1 ON 1 OFF X0 OFF Y0 OFF 0 OFF it Override ON Input Update Force from Programmer Result of Program Solution - L0 User Manual, th Edition, Rev.

11 ppendix : uxiliary Functions UX isplay Error History The L0, L0 1 and L0 PU will automatically log any system error codes and custom messages created with the FULT instructions. The PU logs the error code, date, and time the error occurred. There are two separate tables that store this information. Error ode Table the system logs up to errors in the table. When an error occurs, the errors already on the table are pushed down and the most recent error is loaded into the top slot. If the table is full when an error occurs, the oldest error is pushed out (erased) of the table. Message Table the system logs up to 1 messages in this table. When a message is triggered, the messages already stored in the table are pushed down and the most recent message is loaded into the top slot. If the table is full when an error occurs, the oldest message is pushed out (erased) of the table. The following is an example of an error table for messages. ate Time Message :1:1: *onveyor - stopped :01:: *onveyor - 1 stopped :01:: *Limit SW1 failed :::1 *Saw Jam etect You can use UX Function to show the error codes or messages. You can also view the errors and messages from within irectsoft by using the PL/iagnostics sub-menu. 1 L0 User Manual, th Edition, Rev. -

12 ppendix : uxiliary Functions 1 UX * Handheld Programmer onfiguration UX 1, and Several UX functions are available that you can use to set up, view, or change the Handheld Programmer configuration. UX 1 Show Revision Numbers UX eeper On/Off UX Run Self iagnostics UX 1 Show Revision Numbers s with most industrial control products, there are cases when additional features and enhancements are made. Sometimes these new features only work with certain releases of firmware. y using UX 1, you can quickly view the PU and Handheld Programmer firmware revision numbers. This information (for the PU) is also available from within irectsoft from the PL/iagnostics sub-menu. UX eeper On/Off The Handheld Programmer has a beeper that provides confirmation of keystrokes. You can use uxiliary (UX) Function to turn off the beeper. UX Run Self iagnostics If you think the Handheld Programmer is not operating correctly, you can use UX to run a self-diagnostics program. You can check the following items. Keypad isplay LEs and acklight Handheld Programmer EEPROM check UX * - EEPROM Operations UX 1 - Several UX functions are available to move programs between the PU memory and an optional EEPROM installed in the Handheld Programmer. UX 1 Read from PU memory to HPP EEPROM UX Write HPP EEPROM to PU UX ompare PU to HPP EEPROM UX lank heck (HPP EEPROM) UX Erase HPP EEPROM UX Show EEPROM Type (PU and HPP) - L0 User Manual, th Edition, Rev.

13 ppendix : uxiliary Functions Transferrable Memory reas Many of these UX functions allow you to copy different areas of memory to and from the PU and Handheld Programmer. The following table shows the areas that may be mentioned. Option and Memory Type L0 efault Range L0 efault Range 1:PGM Program $ $0 $ $00 :V V-memory $ $ $ $0 :SYS System Non-selectable copies system parameters :etc (ll) Program, System and non-volatile V-memory Non-selectable Non-selectable UX 1 PU to HPP EEPROM UX 1 copies information from the PU memory to an EEPROM installed in the Handheld Programmer. You can copy different types of information from PU memory as shown in the previous table. UX HPP EEPROM to PU UX copies information from an EEPROM installed in the Handheld Programmer to the PU. You can copy different portions of EEPROM (HP) memory to the PU memory as shown in the previous table. The amount of data you can copy depends on the PU. UX ompare HPP EEPROM to PU UX compares the program in the Handheld Programmer (EEPROM) with the PU program. You can compare different types of information as shown previously. There is also an option called etc. that allows you to check all of the areas sequentially without re-executing the UX function every time. UX HPP EEPROM lank heck UX allows you to check the EEPROM in the Handheld Programmer to make sure it is blank. It s a good idea to use this function any time you start to copy an entire program to an EEPROM in the Handheld Programmer. UX Erase HPP EEPROM UX allows you to clear all data in the EEPROM in the Handheld Programmer. You should use this UX function before you copy a program from the PU. UX Show EEPROM Type You can use UX to quickly determine what size EEPROM is installed in the PU and Handheld Programmer. The L0 and L0 use different size EEPROMs. See hapter for additional information. 1 L0 User Manual, th Edition, Rev. -1

14 ppendix : uxiliary Functions 1 UX * Password Operations UX 1 - UX functions are available to modify or enable the PU password. You can use these features during on-line communications with the PU, or, you can also use them with an EEPROM installed in the Handheld Programmer during off-line operation. This will allow you to develop a program in the Handheld Programmer and include password protection. UX 1 Modify Password UX Unlock PU UX Lock PU UX 1 Modify Password You can use UX 1 to provide an extra measure of protection by entering a password that prevents unauthorized machine operations. The password must be an eight-character numeric (0 ) code. Once you ve entered a password, you can remove it by entering all zeros ( ). This is the from the factory. Once you ve entered a password, you can lock the PU against access. There are two ways to lock the PU with the Handheld Programmer. The PU is always locked after a power cycle (if a password is present). You can use UX and UX to lock and unlock the PU. You can also enter or modify a password from within irectsoft by using the PL/Password sub-menu. This feature works slightly differently in irectsoft. Once you ve entered a password, the PU is automatically locked when you exit the software package. It will also be locked if the PU is power cycled. WRNING: Make sure you remember the password before you lock the PU. Once the PU is locked you cannot view, change, or erase the password. If you do not remember the password, you have to return the PU to the factory for password removal. NOTE: The 0, L0 1 and 0 PUs support multi-level password protection of the ladder program. This allows password protection while not locking the communication port to an operator interface. The multi-level password can be invoked by creating a password with an upper case followed by seven numeric characters (e.g., ). UX Unlock PU UX can be used to unlock a PU that has been password protected. irectsoft will automatically ask you to enter the password if you attempt to communicate with a PU that contains a password. UX Lock PU UX can be used to lock a PU that contains a password. Once the PU is locked, you will have to enter a password to gain access. Remember, this is not necessary with irectsoft since the PU is automatically locked whenever you exit the software package. - L0 User Manual, th Edition, Rev.
